Trying to iMessage another iPhone. Phone number is coming up green email address is blue. How come iPhone number isn't blue.
I have an iPhone 6 and all software is up to date. I am messaging another iPhone and their phone number used to come up as an iMessage, now it is going through as a SMS message. His email comes up as available for iMessage but not the phone number. I have reset my iMessage 3x and it still shows that way. Any suggestions.
iPhone 6s, iOS 9.2.1
